AT'ITMOBILE OILHEATINGy DEVICE.

Application tiled March 15, 1927. Serial No. 175,488.

The invention relates to an oil heater, and more particularly to the class of heaters for the crank cases or oil pans of internal combustion engines, used in automobiles or the like.

The primary object of the invention is the provision of a device of this p character, wherein oil contained within a crank case, oilv pan or the like employed in an internal combustion engine can be heated, from theexhaust of said engine, so that water, gasoline and kerosene contained in the oil .introduced therein by suction from the intake manifold of the engine will be thrown off, so that the oil will be maintained at the required density for thorough lubrication and in this manner the longevity thereof ismain-` tainedat a maximum.

Another object of the invention is the provision of a heater of this .character, wherein the construction thereof is novel in form, so that the same is readily adaptable `for use in conjunction with the crank case, oil pan, orthe like, of an internal combustion engine, without requiring any material alteration in the case, pan or the like, whereby exhaust from the engine can be utilized as the heating medium for oil contained y -within the case, pan or the like, to assure proper fluidity and refinement inthe original quality of the oil for thorough lubrication in its use in the engine.

A further object of the invention is the provision of a heater `of this character, wherein the exhaust from aninternal combustion engine can be controlled for directing said exhaust through the heater vor exeluded therefrom at the option of an operator and when the exhaust is directed'tlirough the heater, it will heat y the oil contained within a crank case, oil pan lor the like of the engine to maintain theoil at Aa temperan ture for the attainment of the best lubricating results, the heater and its adjunct parts being of novel form, to render it adaptable for association with the conventional crank case, oil panor the like, employed with internal combustionengines.

A still further object of the invention is the provision of a heater of this character, which is extremely simple in construction, thoroughly reliable@ and elicient both for heating and 'distilling oil within a crank case, oil pan or'the like, readily and easily applied and removed, durable, and inexpensive to manufacture and install.

case, Aoil pan or the like,

'With these and other "objects in View, the invention consists in the features of construction,lzcombination and arrangement of parts,`as"will be hereinafterniore fully described indetail, illustrated in the accompanying sheet, showing the preferred einbod'iment of the invention, and pointed out inthe claimsZ hereunto appended.

In the accompanying drawing Figure lis a plan view of a crank case,-

oil pany or the like, of conventional type einployed with internal combustion engines, showing the heater constructed in accordance with the invention associated therewith and connected to the exhaust manifold of the engine. V

Figure 2 is a fragmentary vertical longitudinal sectional View through the crank and the heater in association therewith.

`Figure 3 is a sectional View taken approximately on the line 3-3 of Figure 2 looking in the direction of the arrow.

Figure 4 is a fragmentary side elevation showing in .detail valves `controlling the exhaust inthe exhaust manifold of the internal combustion engine.

Figure 5 is a fragmentary view in section.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing, in detail, A des- A ignates generally the crank case or oilcontaining lower section thereof inrwhich is adaptedto be placed the oil for lubricating the crank bearings of an internal combustion valve structure C, provided with a cut-offA valve 12 having its operating lever 13 exteriorly of said structure to be operated in any desirable manner, whereby the valve can be opened or closed at the option of the operator.

The heater constituting the present invention comprises anauxiliary case 14 of greater size than thecase or section A to accommodate the latter when telescoped over thesame, the marginal portion of the case 14 being formed with an outturned continuous flange 15 ada ted to match the flange on the case iiange'l are passed the bolt members 11 for the securing of the cases A and 14 in place in their interitted or assembled relation to site ends opening t each as is clearly shown in Figures 2 and 3 of the drawings.

In assemblinfDr the case 14 relative to the case A there is fbrmed entirely about the bottom, sides and ends ofasaid case A a heating chamber 16, while horizontally disposed within said caseA at its oint elevated from its bottom is a substantially U-shaped heating unit or pipe 17, the parallel legs 18 and 19 of which open through one Side of the casing A and the legl 18 at its free end extends exteriorly for a distance of the casing A to providea coupling 20 for apurpose presently described.

Mounted exteriorly on the case 14 on the side thereof opposite the location of the ex-v' haust manifold B of the internal combustion engine is an outlet ipe 21 having its opporough the side of the case 14 for communication with the cham-v ber 16 between the latter and the case or section A, while medially -of this pipe 21 is a downwardl directedv exhaust or outlet nozzle 22 for the discharge ofA exhaust from the chamber 16, which exhaust is, delivered thereto in a manner presentl described.

Communicating with an leading from the valve structure C is a branch pipe or elbow 23 the latter opening into the case 14 and at this point of opening, the coupling 2O engages therein, so that the exhaust from the manifold B can pipe or elbow 23 into the heatin unit 17 through the leg 18, whence it wil be conveyed through the leg 19 into the chamber 16 and ltherefrom through the pipe 21-and exhaust or-outlet 22 as will be clearly obvious.. l Arranged in the ni ple 24 connectin the pi e or elbow 23 with the structure is a suitable cutoif valve (not shown) adapted to be operated by the lever 25, which thropgh the medium of the link 26 is connected with the lever or handle 13 of thevalve 12, so that both valves can be actuated in unison, but on the opening of the'valve in the nipple 24 the valve 12 will be simultaneously closed in the structure C. This valve 12 is located and arranged to lclose below the ypoint of communication of the elbow or pipe 23 w1th the structure C, so that when the said valve 12 is closed the exhaust in the manifold B will be directed through the heatgr by pass-- and through this be conveyed through` thel ing thrugh the pipe or elbow 23 into the heating unit 17 and chamber 16 between the cases A and` 14, so that oil within the case A will be properly heated to assure fluidity thereto and to distill or eliminate water, gasoline and kerosene which have been drawn into the case A by suction in the intakemanifold of the internal combustion engine. The spent exhaust for the heating of the oil in the case A is let 0E or discharged through the outlet 22 as will be clearly apparent( l On closing the valve in the nipple 24 the exhaust can be shut oif from'the heater and discharged from the exhaust manifold B to the atmosphere in the usual or customary manner as will be fully understood.

What is claimed is:

1. An oil heating attachment for motor vehicles comprising a pan adapted to be arranged in spaced relatin and to completely surround the oil containing section of a crank case of an internal combustion en ine.

and providing in connection therewit a heating chamber, a substantially U-shaped conveyor pipe located within said section and having one of its legs extendinv through oneof th Walls of said section and opening into said chamber and having the other of its legs extending through such wall and said chamber and through a wall of said pan, means for, conveying exhaust from an englne directly to said last mentioned leg, and means connected to one of the walls of said pan for delivering the exhaust from said chamber.

2. An oil. heating attachment for motor ve.
